I am toying with the idea of using one of my Tailscale instances as traditional VPN, using the exit node features. I think I have that part down to a note as far as what has to be done in order for this to happen.
My question is if there are any security risks or security provisions that need to be made to keep the envelope secure. I am the only user of my Tailscale network, so I don’t have to worry about another user jacking things up. However, I am concerned about the implications of the visibility of the exit node I would be connecting to.
Visibility how? You don’t need to open any ingress ports on the VPS instance unless you plan on reverse proxying something back to your client node. Your client visibility will be to any endpoint you connect to, and any DERP servers you get proxied through from Tailscale.
The way I understand it, there’s 2 use cases for a VPN, with different concerns and providers:
Is Tailscale fit for the second? I thought not, as the exit node is not an anonymized VPN server but one of your own machines.
Yes, OP understand that, which is why he is asking about security to the exit node on a Tailnet.
If you create little solar-powered micro computers and toss them onto the roof of a bunch of random businesses with public Wi-Fi, then run them as exit nodes then you could bounce your connection around through a random set.
I didn’t come up with this, I think it was a plot point in some novel I read.
That’s crazy and genius!

I’m sorry…I’m just asking all the stupid questions up front.
They’re good questions. I wasn’t being rhetorical 🤣
It’s hard to know exactly where your concern about visibility lies, hence my question 😉
Nah, it’s good. I do have a knack for asking silly, basic questions. I certainly don’t have the networking prowess and certifications that some of the group here has, and I just want to be cautious, perhaps overly cautious when implementing what I have proposed. I know what an overlay vpn does, and I know what a traditional vpn like say, PIA, does. I just want to proceed with caution because the end use has serious implications if improperly deployed. At the very least I want to make myself confidant that I have covered all bases.
